:confused: Does anyone know about how much a new 350mcx LS1 computer costs? My boat all of a sudden will not start, the gas guage quit and the fuel pump will not come on. I unpluged the fuel pump and ran 12volts directly to the pump and it works, I checked the relays and they are all good. Are there any fuses for the fuel pump? I'm thinking the computer has gone out???

Try your emergence shut off switch. Make sure its working right first.

As 03 35th Anniv indicated, it is the the kill switch until proven otherwise. They can be touchy. Make sure the switch is depressed all the way.

Symptoms sound very much like the kill switch!

OK....little thread-jack...where do you buy a spare clip that attaches the lanyard to the switch. The clip on mine seems to be a bit deformed and doesn't hold the button in all the way.....mine has a single wrap of athletic tape around the "finger" on the clip that holds the button down.

You may have to buy the whole unit and if the clip works on yours, save the switch in case you need it later, or even replace the whole thing now, http://www.skidim.com/prodinfo.asp?number=SIEMP40970

even try putting a jumper on the switch this way you eliminate that all together of being the culprit... I had to replace my ECM just last year on my old boat and it cost me around $1200

Hey guys, thanks sooooooooo much for the replys, the kill switch clip wasn't holding the button down all the way. 2 wraps of tape=$0.00
